HOWARD C. MARMON, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO NORDYKE &

MARMON INDIANA.

COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION OF HEATED ROLL FORFLAKING- MILLS.

Application filed April 8, 1921. Serial'No. 459,780.

7 '0 all whom it may concern Be it known that I, HOWARD C. MARMON, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented a new and useful Heated Rollfor Flaking Mills,'of which the following is a specification.

The object of my invention is to provide an improved steam-heated rollfor the treatment of grains, for the preparation of food products.

The accompanying drawing, which is an axial section, illustrates myinvention.

In the drawing, 10 indicates the main body, or grain-treating portion ofmy roll, in which is formed a comparatively large chamber 11. The mainbody 10 is provided at its ends with .trunnions 12 and 13 which havebores 12 and 13 respectively.

Secured to the end of trunnion 12 by bolts 14 is a cap 15 into which arethreaded pipes 16 and 17 extending from opposite faces of the cap. Pipe16 is considerably smaller than bore 12', is of sufficient length toproject well into chamber 11, and is supported near its inner end by aspider 18 the ends of the arms of which contact with bore 12. Pipe 17 isexternally machined at its outer end and is projected through a packinggland 19 in which it rotates into a supply chamber 20 formed in aconnector head 21 carried by a steam-supply pipe 22 which delivers intochamber 20.

Connector 21 carries a small drain pipe 23 which is of smaller diameterthan the bore of pipes 16 and 17 and is projected therethrough. At itsinner end, pipe 23 is laterally deflected so as to lie in chamber 11well below the axis of roll 10, the deflection being of such characterthat, when bolts 14 are removed pipes 16 and 23 may be readily withdrawnfrom the roll so that the roll may be withdrawn from its bearings (notshown) so that it may be resurfaced or replaced.

The outer end of pipe 23 is carried to a point lower than the inner endand pro vided with a valve 23.

Bore 13 is provided at an intermediate point, with an annular seat 2 1upon which is normally held a valve 25 by 'a'plug 26 threaded into theouter end of bore 13, the

plug 26 and valve 25 being suitable rod or tube27.

In operation steam enters chamber 11 through pipes 17 and 16 as roll 10is rotated becomes condensed in chamber .11, and in a short time risesabout the axis of the roll connected by awhereupon a gravityfiow of thewater is established through pipe 23. By an adustment of valve 23.the'level of the water in chamber 11 is syphoned to approximately a thelevel of the inner end of pipe 23 and there maintained by the syphonaction of pipe 23 so that chamber 11 is'kept practically free from waterduring continued oper- 1 steam supply pipe, projecting into said hollowmain body and being laterally deflected at its inner end, means forsupporting the inner end of saidsteain ing the end of said trunnion andsupporting said steam pipe'and a packing gland pipe, a capclosassociated with the outwardly projecting steam pipe and carried by asteam supply pipe whereby the steam pipe in the bore may rotate with theroll while the drain pipe may .remain stationary.

In witness whereof, I have hereunto set I my hand at Indianapolis,Indiana, April, A. D. one thousand nine hundred and twentyone.
